[expert] reverse DNS

[Pj]

Regarding reverse DNS: I've noticed that some SPAM messages with bogux
names and addresses are using reverse numbers in the message headers. 
the sequence is fake, but the numbers are real. 

If anyone understands how this bogus stuff gets thru I'd like to know.
You can post me privately if you don't want to start a thread.
